Mostly, either the polymer or the fiber, or both, can come from recycled materials.
In addition, coextrusion can significantly reduce material and production costs, and help recycle the used materials [1].
The developed materials provide an effective shell material for co-extruded WPCs.

Isoamyl acetate is a kind of colorless transparent liquid with a pleasant aroma of banana and pear, which is used in perfumery, medicines, paints, printing and dyeing industry.It is a wide range of light industrial production of raw materials,and it is commonly made by acetic acid and isoamyl alcohol esterification which use concentrated sulfuric acid as catalysts in industry[1].
This article attempts to use 1-Octyl methyl imidazole -3-hydrogen sulfate ([OMIm]HSO4) ionic liquids, used reaction-distillation to prepare isoamyl acetate, reaction and separating from the raw materials are proceeding at the same time, meanwhile isoamyl alcohol of high purity was recieved.

Introduction Microstructural design is one of the best ways to enhance the mechanical properties of film materials.
It was found in 1987 that multilayer films deposited alternately by two kinds of materials at nanometer-scale thickness can exhibit an anomalous hardness increase as compared with the individual monolayer films[1].
VC and TiN are widely used protective film materials for wear and tribological applications, meanwhile they both exhibit stable NaCl structure.
